How to know whether my battery is still healthy?

[AndroidUser1234567]

Hello,

I have doubts about my battery's health for the following reasons:

1. It heats up when put to charge.
   
2. It switches off on its own when the battery level is on its own, especially when I use step counters like "Thunderpod" and "Step Step Go".
   
3. It is discharging pretty quickly. It went from 66% charge to less than 15% charge in only about 3 hours as I was installing my apps and restoring my data after having reset the device.

Kindly confirm if my doubts are well founded.

Also, I had submitted my phone (Lenovo K8 Note) to the service center based on these doubts. But all that the service center did was reset it and hand it over to me claiming that they had tested it rigorously and that nothing's bad with my K8 Note's battery.

In this context, is there any objective way to prove to the service center that my battery is indeed at fault? Some possible ways that come to my mind are:

1. Any method to proving to them that the battery isn't being charged up to 4000 mAh, even when the device claims to be 100% charged?
2. Any logs which I can show to the service center suggesting that the device indeed switched off abruptly on its own when the charge was less than 20% because I had opened either of the two apps ('Thunderpod' and/or 'Step Step Go')?

Any possible help in this respect would be greatly appreciated.

Thanks in advance.

I'd recommend you install the Accubattery Pro app:
https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en_US
Unlike some other 'battery optimizer' type apps (something to be wary of), this app is just an enhanced battery records utility so it doesn't attempt to mess with Android's already implmented battery optimization, it just provides a lot more data than what you get using the Settings >> Battery menu. This page has a lot more details:

There's the free version but buying the pay-for Pro version adds more features, including extra charging history stats.

Hi svim,
Are you suggesting that I let the app run on my phone for a few days and then compare the Estimated Capacity with the Designed Capacity?

Your initial questions on your battery indicate you need to get more info on your battery, the AccuBattery app can provide a lot more info on the battery and charging stats. A lot of that data has to be collected and compiled over time. If you're looking for more instant solutions, I don't know what else is available to do that.

Hmm. Got your point.
I charged it to 80% and 2 hours 30 minutes of active use consumed 36% battery. Is it acceptable? I didn't play games. For the most part, I was watching videos using MX player during this time.

Or should i keep monitoring things for a few more days before jumping to any conclusion?

Keep in mind that watching video content is a pretty taxing thing to do on the battery, it involves not just the app (MX Player) but also either software and/or hardware decoding for both audio and video so the GPU (graphics) and CPU (integral audio), plus the display (typically one of the biggest power using factors) are all in more or less constant use. (... also higher res content will require more system resources than lower res content.)
So compare this to, just as an example, your email app, which will typically be running the background but for the most part is idle, periodically activating itself to go online to check for new email messages, and only fully active when you open it to interact with your emailing.
Both tap some power from your battery but just for some perspective the former is a much bigger draw than the latter.
